Question

What is the dimensional formula of Planck's constant / (wave length × velocity)

Answer 1

Answer:

dimensional formula of Plank's constant is ML2T–1

Answer 2

We know that,

Energy = h × Frequency

=> h = Energy/Frequency

Writing dimensions,

$= > h = \frac{ {ML}^{2} {T}^{ - 2} }{ {T}^{ - 1} } \\ = > h = {{ML}^{2} {T}^{ - 1} }$
